Corneal Ulcers: Prevention, Risks, and Modern Treatment Techniques
A corneal ulcer is an open sore on your cornea. It’s considered a medical emergency. Infections are the leading cause. Symptoms include a red or bloodshot eye, watering eye, severe eye pain, and pus or other eye discharge. In severe cases or cases with delays in treatment, a corneal ulcer is more likely to cause vision loss and blindness.
What is a Corneal Ulcer?
A corneal ulcer is a wound-like sore on your cornea, the clear, dome-shaped tissue layer at the front of your eye. Corneal ulcers can happen for several reasons, but they usually happen because of infections.
Your corneas are like a windshield on a car. They protect the inside of your eyes from the outside world. Damage to your cornea can create imperfections that are more vulnerable to infections and other issues. Having a corneal ulcer is like having a crack or chip in that windshield. Corneal ulcers are a medical emergency. They need immediate care because they can cause permanent eye damage, low vision and even blindness (especially without treatment).
Symptoms and Causes:
What are the Symptoms of Corneal Ulcers?
Corneal ulcer symptoms vary widely. The most common ones include:
- Red or bloodshot eye.
- Teary or watery eye (epiphora).
- Eye pain (can vary from mild discomfort or aching to severe pain).
- Feeling like something’s stuck in your eye, like a hair or dust (foreign object sensation).
- Light sensitivity (photophobia).
- Blurred vision.
- Inflamed or swollen eyelids (blepharitis).
- A white or gray spot on your cornea (these aren’t always visible, and even when they are, they can be hard to see without the right tools).
What Causes Corneal Ulcers?
Corneal ulcers can be categorized into infectious and non-infectious causes:
1. Infectious Causes: These are caused by microorganisms that invade the cornea and create ulcers.
- Bacterial infections: Common in contact lens wearers, especially due to poor hygiene or overwearing lenses.
- Viral infections: Herpes simplex virus (HSV) and varicella-zoster virus can lead to corneal ulcers.
- Fungal infections: Occur after injuries involving plant material or prolonged use of contaminated contact lenses.
- Parasitic infections: Acanthamoeba, often found in water, can cause ulcers, especially in contact lens users.
2. Non-Infectious Causes: These ulcers result from trauma or underlying conditions.
- Physical trauma: Injuries from scratches, burns, or chemical exposure can lead to ulcers.
- Dry eye disease: Severe dryness can damage the cornea, increasing ulcer risk.
- Allergic eye conditions: Long-term allergic reactions can weaken the cornea, making it more vulnerable to ulceration.
Risks:
Risk factors for corneal ulcers increase the likelihood of developing the condition. While anyone can get a corneal ulcer, you are at a higher risk if you have:
- Frequent or prolonged contact lens use, especially:
- Sleeping or swimming with lenses in.
- Poor maintenance or cleaning of lenses.
- A history of viral infections:
- Herpes simplex virus (HSV) or varicella-zoster virus (shingles).
- Dry eyes, which weaken the cornea and make it more prone to ulceration.
- Conditions affecting eyelid closure, such as:
- Facial paralysis (e.g., Bell’s palsy).
- Graves’ disease, which causes eye bulging and incomplete eyelid closure.
- Use of steroid-containing eye drops, which can increase infection risk.
- Corneal injury or burn, leading to damage and vulnerability to infection.
- Type 2 diabetes, which weakens the immune system and impairs healing.
- A history of eye surgeries (e.g., LASIK, cataract removal) or pre-existing corneal diseases.
What are the complications of corneal ulcers?
Corneal ulcers can cause the following complications:
- Astigmatism or other vision changes.
- Cataracts.
- Endophthalmitis.
- Glaucoma.
- Perforated or scarred cornea.
- Recurrent corneal erosions (RCEs).
- Vision loss.
Modern Treatment Techniques for Corneal Ulcers:
Modern Treatment Techniques for Corneal Ulcers have significantly advanced, improving outcomes and recovery time for patients. Here are some of the most effective treatments:
- Antimicrobial Eye Drops: Antibiotic drops for bacterial infections, antiviral drops for viral causes (e.g., herpes), and antifungal drops for fungal infections. These treatments are often the first line of defense to stop the infection and prevent further damage.
- Corneal Cross-Linking (CXL): A newer technique used to strengthen the cornea by applying riboflavin (vitamin B2) drops and using ultraviolet (UV) light. This is particularly helpful for recurrent ulcers or those caused by keratitis or other corneal disorders.
- Amniotic Membrane Transplant: A biologically derived membrane placed over the ulcer to promote healing and reduce inflammation. It acts like a natural bandage and is used for severe cases.
- Corneal Transplantation: For ulcers that are resistant to other treatments or have caused significant scarring, a corneal transplant may be necessary. This involves replacing the damaged cornea with healthy donor tissue.
- Laser Treatment (Phototherapeutic Keratectomy – PTK): PTK uses lasers to remove damaged tissue from the cornea, promoting healing and reducing scarring. It is an effective option for recurrent or difficult-to-treat ulcers.
- Anti-inflammatory Medications: Steroid eye drops may be used after the infection is controlled to reduce inflammation and scarring, though they are carefully monitored to avoid worsening the condition.
- Specialized Contact Lenses (Bandage Lenses): These soft lenses protect the cornea from further damage, reduce pain, and promote healing while the ulcer heals with medical treatment.
- Autologous Serum Eye Drops: Made from the patient’s blood, these drops contain natural growth factors that aid in healing severe or chronic ulcers when other treatments are insufficient.
Prevention
Can corneal ulcers be prevented?
Corneal ulcers aren’t completely preventable, but there are several steps you can take to reduce your risk significantly. Here’s what you can do:
- Avoid sleeping in contact lenses: This is the most common cause of serious corneal ulcers. Always remove lenses before sleeping, even if they are marketed as overnight lenses.
- Don’t wear contact lenses beyond their lifespan: Overusing contact lenses increases the likelihood of bacterial growth. Daily disposable lenses are the safest option.
- Maintain proper hand hygiene: Wash your hands regularly with soap and water, or use hand sanitizer with at least 60% alcohol to prevent introducing germs to your eyes.
- Use eye protection: Wearing protective eyewear during activities that could injure your eyes is a key step in avoiding trauma-related ulcers.
- Avoid sharing eye-related items: Never share items like makeup, towels, or contact lens cases that come into contact with your eyes or the area around them.
